Background: Intertrochanteric fractures is the fracture of the proximal femur, in which the fracture line extends from the greater trochanter to lesser trochanter 1

Introduction: Osteoid osteoma mainly occurs in long bones (75%) and represents 2 to 11% of all bone tumors of foot and ankle and, most commonly, in talus. Here, we present a case of osteoid osteoma of neck of right talus, which was presented as chronic ankle pain and was treated with curettage and cancellous bone graft.Case report: A 19-year-old patient presented to us with chronic right ankle pain on anteromedial aspect of dorsum of right ankle with difficulty in walking. Plain radiograph of right ankle joint revealed sclerosis in neck of talus. Both computed tomography (CT) and magnetic resonance imaging (MRI) were suggestive of osteoid osteoma involving superior aspect of talar neck. An incision was made over anteromedial aspect of dorsum of right ankle. Curettage was done and cavity was filled with cancellous bone graft from iliac crest. Patient was advised nonweight bearing for 4 weeks and physiotherapy.Discussion: There is difficulty in diagnosis of osteoid osteoma of talus. The time delay in diagnosis is about 2.5 to 10 years. In our case, it was about 4 years. Radiograph features include small radiolucent area (nidus) with surrounding sclerosis. A CT is the best method for diagnosis. Rashid et al 5 had done subtalar arthrodesis with curettage. Assafiri et al had done arthroscopic resection. In our case, we performed curettage and cancellous bone grafting. Conclusion:A high index of suspicion of this disease should be held while treating patients with chronic ankle pain. A CT scan is the best method to identify the nidus. Although multiple treatment modalities are available, open resection with curettage and cancellous bone graft showed good result in our case.
